Lasermate offers InGaAs (indium gallium arsenide) PIN photodiode chips and arrays that are used for detecting light in the near-infrared region and commonly used in telecommunications, fiber optics, and spectroscopy applications. As compared to silicon photodiodes, InGaAs photodiodes exhibit higher sensitivity in the near-infrared region. We also supply packaged InGaAs photodiodes and InGaAs fiber-coupled receptacle/pigtail assemblies.
